Product Specifications and Features


The Seaflow S13B automatic bilge pump is a reliable pump designed to efficiently remove water from your boat's bilge. This model is supplied as OEM part number 1G110013B, allowing straightforward integration with existing boat systems.

With a 12V motor, the pump can move up to approximately 1100 gallons per hour (GPH), providing quick and effective drainage. It is suitable for dealing with rainwater, seawater and other bilge water on board.

The automatic operation activates the pump when the water level reaches a set height, helping to keep the bilge dry and reduce the risk of damage to your boat. This also removes the need for frequent manual switching.

Constructed from corrosion resistant materials, the Seaflow S13B bilge pump is designed for use in the marine environment. Its compact size makes it suitable for installation in tighter spaces on a wide range of boats.

Seaflow is known for producing dependable marine equipment, and this automatic bilge pump is intended to provide consistent performance in everyday use.
